VEHICLE-WHEEL.

aeoaaa.

To all whom it may concern:

Be it known that I, CI-IARLEs M. BACK- MAN, a citizen of the UnitedStates, residing in Los Angeles county, California, have in vented a newand useful Vehicle-Wheel, of which the following is a specification.

My object is to improve the details of a roller bearing wagon axle; andmy invention consists of the novel features herein shown, described andclaimed.

In the drawings: Figure 1 is a fragmental elevation of a vehicle wheelembodying the principles of my invention, as seen from the outside andas indicated by the arrow 1 in Fig. 2. Fig. 2 is a sectional detaillongitudinally of the axle and taken on the line 2--2 of Fig. 1. Fig. 3is an enlarged sectional detail on a plane parallel with Fig. 1 andtaken on the line 3-3 of Fig. 2. Fig. 4 is a View in elevation of one ofthe housing plates carrying the bearings for the rollers. Fig. 5 is aview in elevation of the other housing plate carrying bearings for therollers, the plate shown in Figs. 4 and 5 when put together serving as ahousing for the rollers. Fig. 6 is a View in elevation of one of theaxles. Fig. 7 is a view in elevation of the nut fitting upon the axleshown in Fig. 6.

Referring to the drawings in detail the axle tree 1 is fixed rigidly ininner shell 2. Spokes or webs 3 extend radially from shell 2 and thebearing shell 4 is formed upon the outer ends of spokes 3. The flange 5extends from the inner end of outer shell 4 and screw threads 6 areformed upon the outer end of the outer shell 4. The inner shell 2, theweb 3, the outer shell 4, and the flange 5 are or may be cast integral,and the periphery of the outer shell 4 is turned and finished concentricto the axle tree 1, and nut 7 fits upon the screw thread 6.

In Fig. 1 I have shown a wagon wheel having my spring rim as shown,described and claimed in my application for spring wheel, filed July 13,1910, #571,693, and I do not wish to claim the spring wheel feature inthis application.

In constructing the hub for my present invention the wooden ring 8 isprovided with an external band 9 and the inner spoke sockets 10 areprovided with ears 11 and 12 to fit against the sides of band 9 and thewood rim 8, and the bolts 13 pass through the ears 11 and 12 and throughthe wood rim 8 to hold the spoke sockets 10 in place.

Specification of Letters Patent.

Application filed August 22, 1910.

Patented J an. 3, 1911.

Serial No. 578,413.

The spokes 14 extend from the inner spoke sockets 10 to outer spokesockets 15, said outer spoke sockets being secured to the outer woodenrim 16.

The roller housing A comprises the annular housing plate 17 fittingtightly in the wooden rim 8, and having teeth 18 extending into the woodto prevent rotation of the wood relative to the housing plate; therebeing roller chambers 19 bored from one end face of the plate 17, nearlythrough the plate and leaving bearings 20 to receive the pintles of thebearing rollers; there being screw threaded holes 21 bored from the sameface as the bearing chambers; and the second housing plate 22 fittingagainst the end face of the housing plate 17 and closing the ends of theroller chambers 19; there being bearings 23 in alinement with thebearings 20 to receive the opposite pintles of the rollers; and therebeing openings 24 and screws 25 inserted through the openings 24 andscrews seated in the openings 21 to hold the second housing platerigidly in place. The bearing rollers 26 are placed in the rollerchambers 19 with their pintles in the openings 20 and 23, said bearingrollers engaging the periphcry of the outer axle shell 4.

I desire to call especial attention to the fact that I have enlarged thediameter of the axle bearing and correspondingly enlarged all of theworking parts, and that there is a circulation of air between the innershell 2 and the outer shell 4 to keep the axle from heating.

Bolts 27 are inserted from the interior. of the wood rim 8 outwardlythroughthe wood rim and screw seated in the inner ends of the spokes 14;the heads of the bolts being recessed into the inner face of the woodrim.

The flange 5 and the nut 7 are larger in diameter than the housing plate17 so as to form close joints with the wood rim 8, there by excludingdirt from the bearings.

I claim:

1. In a vehicle wheel, a wooden. rim, an iron band around the woodenrim, spoke sockets against the outer face of the iron band, earsextending inwardly from the spoke sockets on each side of the iron bandand the wooden rim and secured in place, spokes in the spoke sockets,-bolts inserted from the interior of the wooden rim through the woodenrim and iron band and screw seated in the ends of the spokes, a rollerhousing fixed in the wooden rim, rollers in the roller housing, axlespokes extending outwardly from axle, a shell upon the spokes andfitting against the rollers,'a flange extending outwardly from the innerend of the shell past the roller housing to the Wooden I'lIH, and a nutscrew seated upon the outer end of the shell and extending outwardlypast the roller housing to the Wooden rim.

2. In a vehicle Wheel, an axle, spokes extending outwardly from theaxle, a shell upon the spokes concentric to the axle, a flange extendingoutwardly from the inner end of the shell, a nut adapted to he screwseated upon the outer end of the shell, a

roller housing, rollers in the roller housing 15 CHARLES M. BAGKMAN.
